Caution

Always connect the system separator to

the water supply, never directly to the appli-

ance!

 Connect the supply hose to the water

connection point of the machine and at

the water supply point (for e.g. a tap).

 Open the water supply.

Note

The supply hose is not included.

 Danger

Never suck in water from a drinking water

container. Never suck in liquids which con-

tain solvents like lacquer thinner, petrol, oil

or unfiltered water. The sealings within the

device are not solvent resistant. The spray

mist of solvents is highly inflammable, ex-

plosive and poisonous.

 Connect suction hose (minimum diame-

ter 3/4“) with filter (accessory) to the

water connection point.

 Set dosing value for detergent to "0".

 Remove air from appliance before oper-

ation.

Note

Do not use the Geka coupling (included in

delivery) for vacuuming! Not all connector

couplings are suitable for vacuuming

(pump sucks air and therefore does not

build up pressure).

 Open the water supply.

 Start the engine according to the oper-

ating instructions of the engine manu-

facturer.

 To dearate the appliance, unscrew the

nozzle and allow the appliance to run

until the water exits in a bubble-free

state.

 Switch off the appliance and fit the noz-

zle again.

 Danger

– Place the appliance on firm surface.

– The high pressure cleaner must not be

used by children. (Risk of accident on

account of improper use of the appli-

ance).

– The high pressure spray generates high

levels of noise when the appliance is in

use. Risk of hearing impairment. Al-

ways use proper ear-protection aids

while working with the appliance.

– The water jet coming out of the high

pressure nozzle causes the gun to re-

coil. Further, an angular spray pipe can

cause additional torque. Hence hold the

spray pipe and gun firmly.

– Never direct the water jet on to persons,

animals, the appliance itself or electrical

components.

– Vehicle tyres/ tyre valves may be

cleaned only with a minimum spray dis-

tance of 30 cm.

Otherwise, the high pressure spray can

cause damage to the vehicle tyre/ tyre

valve. The discolouring of the tyre is the

fhe first sign of damage. Damaged ve-

hicle tyres are a source of danger.

– Do not spray materials contains asbes-

tos or other health-hazardous sub-

stances.

– The operator must wear proper safety

gear to be protected against the water

sprays.

– Pay attention to ensure that all screws

of all connecting hoses are tightened

properly.

– The lever of the hand spray gun must

not be locked during the operation.

– Do not spray flammable liquids.
